Skater’s start errors

Skater’s start errors:
۱- When starting, you must have one leg fixed inside the box if the skater’s foot is removed from the box, the start error will be considered.
۲- Skater must turn on the sensor when the first leg has been removed from the ground.Otherwise,it is an error for him.
۳- (In K.O part) , Skater must remain motionless behind the start line before the “Beep” is heard (muscle contraction with stability). Otherwise, it is an error for him.
